I hear you.
I'm self taught.
I was always the go to guy when there was a problem.
I had no one I could ask.
Teachers asked me.
But no one hired me.
So I became self employed.
I wonder how much better I would've done if I actually went studying and had a mentor.
But I was always on the frontier, always.
I also fixed so many bad student projects, aka where someone would hire a student for cheap and the student would abandon the project and I had to step in to finish it.
Ah well it is what it is.
Nowadays I feel like an outsider, probably because I am. Still being self employed but my projects crashed and income is way below sustainable.
So either create something new, but I'm getting old and tired and bored, or find a job, but I'm too used to the comfort of working when I feel like it and not being on a clock.
Anyhow I digress and if I had a proper teacher in my young years, how much better could I have done. I'd imagine an increased learning speed of factor at least 5 if not 10. Also not studying means not knowing the language e.g. log(o) or w/e. I never knew what "scalar" meant when I read it, but I knew without having a label "scalar". etc etc
